ⓘ  What happened

Microsoft's April 2026 security update introduced stricter driver signature validation as part of a broader effort to improve Windows security. This industry-wide change removes trust for older cross-signed driver certificates used by many hardware vendors, including XIMEA. As a result, some USB camera drivers may now be blocked by Windows. This is caused by external operating system security enforcement and does not indicate any defect or malfunction in XIMEA hardware or software. The update is rolling out gradually across Windows 11 systems, so affected users may see the issue at different times.

🔍  Root cause

The affected systems are rejecting older USB driver packages because Windows now enforces stricter verification of driver signatures. The camera hardware is not the source of the failure. The issue is resolved by installing a USB driver package that complies with the newly enforced Windows driver verification requirements.

🖥  What this means for you

On Windows systems where Microsoft has already deployed this specific security update, XIMEA USB cameras using an older affected driver may fail to initialize. XIMEA PCIe camera products are not affected by this update and remain fully operational.

🗎  Permanent fix and update options

XIMEA has released a permanent fix in USB driver 2.0.9. Please choose the update path that matches your system constraints:

After installing the updated driver or API package, reconnect the USB camera and verify that it initializes normally.
